I spent four days here summer of 17. Well maintained sites. Lots of hiking opportunities. Both modern and rustic camping available.
I have stayed there twice in the last two years. Its poorly maintained especially for the cost of the site per night. I used this park regularly 20 years ago. Much of it can be blamed on DNR cuts but some of it is poor management. I was also offended by the double standard of rules enforcement. There is s group called “Friends of Sleepy Hollow”, who proudly display their signs in front of their motor homes. I suspect this was a well intentioned organization. But their members get a pass from the ranger regardind quiet hours, yet jumps at any of their concerns. The whole park is over grown and understaffed. I have had much better camp sites in rustic campgrounds around the state.
